WebApr 13, 2016 · A hash is a function that produces a digest from a message. A cryptographically secure hash is for which it is computationally infeasible to generate a message with a given digest. On its own a hash of a message gives no information about the sender of a given message. WebFeb 3, 2024 · A cryptographic hash is a checksum or digital fingerprint derived by performing a one-way hash function (a mathematical operation) on the data comprising a computer program (or other digital files). Any change in just one byte of the data comprising the computer program will change the hash value. The hash value is, therefore, a unique ...
